Face scrubs/wash

Apologies for slightly incoherent post (late night trying to do online shopping) - I am told that the micro beads in exfoliating face washes can't go through the filters in the sewage. If this is so I am since I love them, whether or not they actually work (suffer from acne still even tho I'm over 40 ), I just like the feel of them. Is there a brand that is environmentally ok or will otherwise have the same (basically psychological) effect?
